How to manga to anime?

Forget the manga plot and all that stuff. It's not really a manga but a story i wrote and friend sketched. We wish to make a MV with it but we want it to look like an anime. Colored, have that anime quality, but we are not familiar with the process is it shot by shot and then we scan it and piece it together? Or what? We really want color as the song is slow and if it's just sketches I think the video wouldn't be very good. Please answer. Thank you!
